Volume 1: Sino-Japanese War Chapter 70: The idea of ??gunnery

Previous page        Return to Catalog        Next page

    In fact, Lu Hong had an idea for the overall transformation plan of the Nari ship after he boarded the battleship. However, this battleship transformation is not as trivial as making a machine by himself. Every time you smash it, you will get money.  It cost more than 20,000 silver to paint and purchase a rapid-fire cannon for training. No matter how much more it was, even if it was sold to Lu Hong, it would be gone.  Therefore, after visiting the Jiangnan Shipyard, Lu Hong drew a simple drawing and asked the craftsmen in the shipyard to make a small thing. It was hung on the cross with a vertical cone. Below are the scales for the front, rear, left and right.  Then he installed this thing on the main gun platform Lu Jianzhang obviously saw this thing, which made him somewhat strange. This thing was definitely not original but he didn't know what it was!  "This is a level!" Lu Hong obviously saw the strange expressions of the two people. He had never thought about replacing the main gun of Nan Rui. Unless Liu Kun came out with the money, he would have to do this money-burning thing on his own.  Warships are not yet certain to go bankrupt, but it is obviously inappropriate to make small fuss.  "Sircould this have something to do with artillery?" Lu Jianzhang and Qi Fengyi were obviously completely confused about what Lu Hong installed next to the fort, but they still had some vague guesses.  Lu Hong stood in front of the fort and took out a blueprint and handed it to the two of them. On the blueprint, there were several schematic diagrams of the changes in the barrel elevation angle of the artillery as the battleship rolled and undulated. Lu Jianzhang and Qi Fengyi understood this little thing almost at the same time.  The function of the device In the firing of artillery, a half-scale difference in pitch angle is a fatal error. Obviously, when the navy originally practiced gunnery, it chose to reduce the ship speed to minimize the occurrence of this situation, and with this  With a small level gauge, you can predict the horizontal position of the fort and fire the artillery at the best position!  Lu Jianzhang and Qi Fengyi were both naval instructors, so they naturally understood the amazing value of the schematic diagram on this paper. The two of them discussed it for a long time, but they still had to raise many questions For example, there was a delay in firing the artillery.  The problem is that the artillery of this era does not fire with just one pull. After ignition, because the black powder burns slowly, it will take a while before firing!  For example, the hull rolling left and right and ups and downs will obviously also affect the position of the level. How to overcome this? Could it be that if this thing doesn't move to the center position, it can't fire For these two guys to understand so quickly  Lu Hong also nodded with satisfaction at the gunnery command chart he drew, "Lang Zhai, haven't you ever been an instructor? Can you briefly talk about the situation of naval gunnery!" Speaking of the navy that Lu Jianzhang is familiar with,  During the drill, he immediately became energetic and used the 210mm Krupp heavy gun in front of him to demonstrate the so-called gunnery skills of the Nanyang Navy and even the entire Chinese Navy. This made Lu Hong scratch his head after listening to it Aiming is mainly based on  When it comes to aiming the gun, you just use your eyes to see if the gun barrel is on the same plane as the enemy ship. If it is not aligned, turn the rotary table As for the pitch of the gun and the timing of firing, it all depends on experience!  Such so-called artillery skills really rely entirely on the accumulation of experience in daily training. When it comes to experience, this time, even the very confident Lu Jianzhang had a somewhat embarrassed expression. You know, this naval test gun is here.  In peacetime, it is really not possible to train if you want to. When Guo Baochang was the commander, he stipulated that the main battleships should practice 5 rounds of artillery every month. In fact, in most cases, they may not even be able to practice 2 rounds of artillery every month. This is  The training fee has to be deducted from the band's sailing expenses, so what will the band have to do with their own money?  As a result, a bizarre situation occurred. During the training, the navy had no intention of practicing at all. But when they came to the peak for the test, the target ship and target were tampered with, with built-in explosives. They even used ropes to measure distances.  The so-called artillery show was just a show This did not surprise Lu Hongduo. He had seen these things in history books before!  After listening carefully to Lu Jianzhang's introduction, he thought about it, and then said categorically to the two of them: "You must completely abandon the past artillery skills. You must master the new artillery skills as soon as possible. In the past two days,  You first urge the workers to paint the ship and install the fast guns, and then come to me. The navy's gunnery must be comprehensively reformed!" Now that the hardware of the warship cannot be greatly improved for a while, it is obvious that Lu Hong naturally  Attention turned to the improvement of naval technology!  In this era, naval gunnery is obviously a key element for victory at sea, and the British Empire is obviously far ahead of China and Japan who are about to go to war in this regard. The British have never been stupid Although the British Empire desperately sells their various weapons to other countries  type battleship, however, the Ministry of the Navy has never stopped researching naval gunnery, and has never actively sold any gunnery-related instruments to external parties.  On the Yoshino recently sold to the Japanese, in view of the strong request of the Japanese, the Armstrong factory installed the first-generation wheat that has been phased out by the Royal Navy.Kermit rangefinder, this kind of optical rangefinder, can maintain a certain range measurement accuracy within a distance of 2000 meters. However, within 2000 meters, direct gun sighting and prediction can already solve the problem of hit rate. Of course,  , this is without considering a series of issues that affect shooting accuracy.  Since 1893, the Royal Navy has been equipped with the FA-MKI vertical Marlock rangefinder of the British company Barr Stroud. This more advanced rangefinder has a standard 8-foot ranging baseline.  , the combined image lens technology is used to determine the distance of the target. At a distance of 3,000 meters, the distance measurement accuracy can reach an error of 1-2%. This is a technology that is very close to mature technology.  When Lu Hong and others were very involved in discussing how to improve naval gunnery skills on the battleship, Lu Jianzhang and Qi Fengyi were all officers familiar with naval military affairs. From their detailed introductions, he soon discovered more  The problem is that there is no concept of wartime damage control on warships. There are neither full-time personnel nor full-time training.  Speaking of this, these two guys even plausibly argued that if a problem occurs, nearby sailors and soldiers will naturally invest in emergency repairs Lu Hong had nothing to do with the unprofessional attitude of these two guys, but he still made a very serious request.  They were preparing a damage control team, and they began to think about going back and writing a pamphlet to quickly assemble the team!  Just when a few people were talking in a lively manner, a fast horse galloped down from the dock. Feng Hesheng sat on the horse and shouted loudly: "Sir Lu, the Imperial Envoy King is anxious to see you. I heard something big has happened!"
